Question

connor is putting in a gravel driveway. it will be 30 feet long and 12 feet wide. connor wants the gravel on the driveway to be about 1/2 foot deep. volume of rectangular prism = lwh
l = length
w = width
h = height
what is the approximate volume of gravel that connor will need for the driveway?
180 cubic feet
240 cubic feet
360 cubic feet
720 cubic feet

Explanation:

Step1: Identify the values of l, w, h

Length \( l = 30 \) feet, Width \( w = 12 \) feet, Height (depth) \( h=\frac{1}{2} \) foot.

Step2: Apply the volume formula for rectangular prism

The formula for the volume \( V \) of a rectangular prism is \( V = l \times w \times h \). Substitute the values: \( V = 30\times12\times\frac{1}{2} \).
First, calculate \( 30\times12 = 360 \), then \( 360\times\frac{1}{2}=180 \).

Answer:

180 cubic feet
